The problem is not just the decompresser size itself, but how much
memory it uses. LZO is pretty special (though not unique) in that its
requisites in that area are very low; as low as just the source and
destination buffers. With LZMA (and other algorithms) we would need
intermediate buffers and other memory-consuming things like dictionaries
and such. I'm neither a compression expert nor an assembly guru, but the
tradeoff might not be up to the task.
